PTFE Piston Seals and Rod Seals - Long lasting, Low friction

PTFE piston seals (PTFE rod seals) as Spring-energized seals and memory packings are always the ideal choice for sealing static or dynamic pistons and rods.

ElringKlinger Engineered Plastics is manufacturer of PTFE seals and offers a broad range of standard PTFE piston seals and PTFE rod seals, supplemented by customer-specific special solutions.

In this area, the focus is on modified PTFE materials and compounds with specifically adapted properties.

• Outstanding dry-running characteristics
• Low wear
• Low friction
• Variable friction conditions through choice of spring characteristics
• Extremely low breakaway forces even after prolonged downtimes
• No stick-slip effect even at low sliding speeds
• High dimensional stability
• High chemical and thermal stability
• No volumetric change by swelling or shrinkage
• Compact seal, suitable for O-ring assembly spaces in acc. with ARP 568 A, DIN 3771, and ISO 3601/1
• Good cost-benefit ratio
• Dimensions from Ø 2 to 3,000 mm available
• Very good wiping effect with abrasive media, such as paints and lacquers
• Sterilizable
• Easy to rinse
